This is probably a bug in the tabbrowser code of Firefox:
https://searchfox.org/mozilla-central/rev/da6a85e615827d353e5ca0e05770d8d346b761a9/browser/base/content/tabbrowser.js#3765-3767

But I wonder why no tab is passed into the removeTab function. This failure comes from a beta simulation job on try.
